  1. I have an Öhlins SD100 with 120mm stroke,

    a SD110 with 90mm stroke should be optimal

    but I got the SD100 cheap :P

     

    It is a world of difference between the Bitubo and the Öhlins,

    the Bitubo makes the steering heavy, the Öhlins unit does it's

    job when it is needed without being noticeable when not needed.

     

    Attaching a list of Öhlins universal SDs

    I also have my original Bitubo lying around

    give me an offer. :grin:

  2. or else we'll only see and hear about raised handlebars, lowered footpegs, hardcases, gel padded seats, etc. ;)

    Nothing of that will ever touch my bike :grin:

    Garage season has begun, plans are layed,

    pictures will be posted when I have something to show :luigi:

    but don't hold you breath :luigi::drink::luigi::drink::luigi::whistle:

  3. I have the red Paddock stand which is very useful when working on

    the engine since it is out-of-the-way.

     

    A little trick:

    Before I remove the front wheel on either of the bikes,

    I secure it by hanging the front of the frame to a beam

    in the ceiling of the garage. If it should fall it doesn't "fall down".

  4. Moved the answer to this thread:

     

    Göran,

    Thanks.  Hey, I've been meaning to ask.  What is up with that fighter pilot helmet?  Is it a standard agv feature to have the 'mask?'  It even appears to be camouflaged in case you have to bail out in the jungle.  :blink:

     

    It's my old AGV Quasar racing :helmet:

    with Max Biaggi design

    Of course Max is sponsored by Suomy today but that just make

    my helmet cooler :rasta:

     

    The face mask came with the helmet. It is removable.

    I use it when temperature drop below +20 Celsius

    (which is not uncommon here in northern Sweden)

     

    Last summer I normally used an open helmet which is

    comfortable when running short distances or in town.

    It has been so many accidents lately so I have given up

    on comfort and always put on full protective gear.

    Racing helmets are not comfortable, they should have a

    very tight fit and I have to fiddle with my glasses every

    time I take it on (and off). Contact lenses, next season.

    BUT I should feel comfortable (= safe) in anything else

    than racing gear.

  5. Don't worry too much,

    check the oil stick, if the "milk" is visable on that change the oil

    otherwise just keep you service intervals.

    I also live in a cold and sometimes rainy climate,

    I always changes oil between riding seasons.

     

    The oilsystem is not a closed system so it is normal the get some

    moisture into the oil. If it is just a few drop it vaporize when the motor

    gets warm and cause the phenomena you describe.

  6. Most experience porters are autodidacts or have learned

    by working with people who knows this stuff,

    there is no university of motor tuning. :luigi:

     

    There are many examples where traditional "flow porting"

    has worked very well, but there are examples here

    in Scandinavia both in road-racing and drag-racing

    where Motoman's "velocity porting" have been used

    with great results. :huh2:

  7. I'm hearing "Ohlins."

    You should be hearing Öhlins

    but you don't have that key on your keyboard I guess. :grin:

     

    It is pronance like the vocal in the particle "an",

    says: "ön Öhlins fork", great party trick :not:

  8. MG recommends a few drops (2 cc) in the rear drive oil,

    it reinforce the oil while heat and high pressure puts the oil

    under heavy load.

    A few drop in the gearbox won't hurt either since we have

    dry-clutches, don't use it with wetclutch.

    I would not put any such additive in the motor oil since

    motor oil have to flow through channels without restiction

    while transmission oil are almost stationary.

  9. I don't remember the side stand switching off the head light.

    In fact I think I lost power to start the bike by accidently

    leaving the head light on while taking a break.

     

    Maybe there are diffences in wiring between diffent years or

    between my euro-guzzi and your "american goose".

  10. Usable power is the key... :bike:

    using a less than optimal suspension setup

    to get more power certainly reduce the usable power.

    A local Harley rider has a tuned motor with 100+ hp wasn't

    able to outrun me on the BSA with less then half of that,

    cause his bike handles like sh*t :bbblll:

  11. This is my procedure:

     

    1. check sag, adjust if possible,

    back end has adjustable preloading, the Marzocchi don't.

    2. set all C and R very soft 1st or 2nd click, test ride and adjust

    R until it stop rocking

    3. adjust C until the front feels stable but not hard. We wan't to catch

    bumps and such but just that, no excessive movement

    4. set C very soft on the back, test ride again and and adjust as 3

    until the bike feels balanced.

     

    Usually I wind up with softer than stock since I ride on some

    bumby roads, but too hard settings does worsen the handling much

    more than too soft ones.

     

    C = compression, R = rebound

  12. al:

    I use an universal damper, partno SD 100

    it has 120 mm stroke, but since the bitubo

    only has 80 mm stroke it points out a bit (no biggie)

    I think an univeral Öhlins with 90 mm stroke should

    be the ultimate choice, partno SD 110

     

    baldini:

    no head shake, but friends of mine have had sudden

    scary experiences on otherwise stable bike.

    Better save then sorry, and since the unit from Öhlins

    does not restrict me at all I feels like a good investment.

     

    I put the 2003 Öhlins catalog

    on my site for your pleasure :luigi: . Warning! Not suitable for sensible persons,

    this is hard core bike porn :D

  13. I add a reply to this old thread instead of starting a new,

     

    Previously I have mentioned that I removed the stock Bitubo steering damper

    and found the bike much "lighter" to handle with no loss of stability.

    But there is always the danger of tank slap when running without one.

     

    Late in this season I mounted a Öhlins damper on my V11

    and I can only say it is great. With loose to medium setting

    it is not noticeble, it is just like running without.

    This is what we want added safety and no ill effects.

    Pricey, yes. Luckily I found a 2nd hand damper at a resonable price.

  14. I probably go for something based on Supertrapp Megaphones

    like this:

    ducati_fly.jpg

     

    but the shaft drive make the arrangement a bit unsymmetric,

    so I am just looking at alternatives. One idea is use 3" Supertrapp IDS2s,

    T1_slipon.gif

    which are very slim and should fit between the subframe and the rear wheel.

     

    But it is 90% chance that I will go with the classic megaphone look,

    at least this winter.

     

    The riding season is probably over now here up north :(

    the garage season begins as of now.
